Problem
The changes have been saved but the calendar still shows the old information.
Possible cause
The calendar normally updates automatically, but a slow connection or a temporary issue may delay the update.
Solution
Reload the page.
Check that the save completed correctly — a success message should have appeared.
Check that you are looking at the correct date in the calendar.
If the problem persists, contact support and include details about:
The class name and date.
Which changes are not showing.
When the issue occurred.
